Not OP, but I don't think they were making fun of the legitimate issues. There have been plenty of instances of pronoun-related overreactions in and outside the tech sector - see the recent-ish StackOverflow mess for an example. There are obviously many issues, but there are also many overblown non-issues and I don't see much harm in making fun of those.
Some people make jokes and don't realize the effect they have on the people who have to be the victims of those comments day in and day out. I'm sorry if that's not easy to understand. These are the same people who think women don't belong in tech, or that people who choose pronouns are "snowflakes". It's why we don't have as many women in tech and it really needs to stop.
